This invention relates to rock drills, but more particularly to a driving device adapted to be'actuated by a rock drill for driving a hollow member, such as apipe, into the softstrata overlying the rock intended to be drilled.

The objects of the invention are to eliminate the necessity of removing the soft ma- I terial or overburden overlying the rock in- '1 tended to be drilled. and to prevent the entrance of loose material into the drill hole prior to the charging-thereof. I

Otherobjects will be-in part obvious and in part pointed out hereinafter. 1 I

lowing description,

Figure l is an elevation of a drill wagon and a rock drill illustrating apractical application of the invention,

Figure 2 is a transverse view takenthrough Figure 1 on the line 22 looking in the direction indicated by the arrows,

Figure 3 is a sectional view taken through Figure 2 on the line 33 looking in the direction indicated by the arrows, I

Figure 4 is a transverse view taken through Figure 1 on the line 4:4, andv Figure 5 isan enlarged elevation of the guide plate illustrating the manner in which they may be clamped to the guide frame.

Referring more particularly to the drawings, A designates a drillwagon having a frame B comprising a pair of vertical guide members C on which is slidably mounted a carriage D supporting a rock drill E. v

I At the upper end of the frame B is a shaft F on which are mounted a pairv of sheaves Gr and H overrun by cables J and K respectively. One end of the cable J is secured to the frame D and the other end may be wound on a motor hoist L mounted on the drill wagon A for raising and lowering the drill E. i

In accordance with the present invention, means arejprovided for driving a drill pipe 0 through the ground P overlying rock Q, intended to be drilled. These means comprise a drive head R interposed between the front end of the drill E and the rearward end of the pipe 0. The drive head preferably has In the drawings accompanying the fola recessS to receive the end of the pipe and a bore T coaxial with the recess S to enable the drill steel T to extend therethrough. Means such as a set screw'Uthreadedinto" thedrive head It maybe used for clamping 5 5 the pipe Oto the drive head; v

In orderto maintain the drive head. Bin operativepositionwith respect to the'drill E said drive head is provided on opposite sides with guidewaysV .to receive ,slidably the guide members VG ofthe frame B. On one 7 side of the'drive head R issecured an eye-bolt \V to-which one endof the cable-K maybe attached. The other end of the cable K may bewound on a motor hoist X disposed on the drill Wagon A for raising and lowering the drive head R.

Means are provided forguiding the pipe 0' near .thepoint at which saidpipe enters-then ground P. These means comprise a pair;ofi7 0 plates Y and Z having curved'portions b and p 0 which cooperate toserve as aguide for the pipe 0. To the end-that the plates Y and'Z may be readily clamped totheguide'mem-F hers C;the plate Z is provided with-a pair ofapertures-d through which extendtongues ecarried by theplate Y. The tongues e preferably have oblong apertures f for the; reception of wedges 'j which; when driven into positionzin the apertures 7, will clamp so the plates and Z firmly against'the guide members C and maintain said plates in that position unaffected by the vibration setup I sists of two pieces, a body portion 0 and c what may be termed a bit 2'0. The bit 39 is secured to the body portion 0 by means of a threaded connection 9 and has an inner tapered surface 9 at its front end to form a knife edge 8 for the purpose of directing the loose soil into the pipe 0 through which it may pass into the drive head R and thence through lateral holest to'the surface of the 7 ground.

Preferably the cutting bit of the drill steel T extends sli htly in'advaneeof thebit p of the pipe j In th isw ay the material through which the pipe passes is gradually displacedandonly a small portion of material will therefore have to be removed by the knifevedge s of the bit pi I I Thedpef'atioii of the deid'e is'as follews P After the drive head R has been disposed on the guidejmernbers .C and raised tq a position v Sem it'fabutisf jtlie'front ad erse-reek .drill E'the O with 'tliefldr'ilhs'teel' I therein maybe placed in operative pesition so that the upper end of the pipe Owill extend into the recess S Wherein-it mey-ibe clamped by the set screW.U. 7 After these partshzive'beenassembled in' 'th'e manner deseribedtliecla nrp platesY and Z are clamped t-oithe' iron-tend o'f thegui-de membericb V 'meahsbf the" Wedges The drilling apps siratus ma then be set in operatio'n an'dethe pipe Ov will be driven thro'lig gl'rtlie groundP hun'tiil the bit" p restsbn the-"rockQi The set scrvv: U may be unscrewed and the drilling apparatus togethenwith the drive head It may be raised byrneans of the motor hoists L j and X: After the "drillhole is completed the cl'ziinpw'rnembers Y and Z are'disc onnected mm the frarhe B the drilling apparatus may be refiioved to another site; 1 Thepipe O .igimdy rerhain in the strata-P until the hole has v beenc harged. 1;
